SPECIFICATION forming part of Letters Patent No. 777,481, dated December 13, 1904 Application filed February 21, 1908. Serial No. l i tufll. (No model.)

To all who/1t zit 'n m l (so/warn.-

Be it known that LI, EDWIN (f. MUMMnuY, a citizen of the United States, residing at Detroit, county of WVayne, State of lvlichigan, have invented a certain new and useful improvement in Hydrocarbon-Burners and WVater-Feeds Therefor, of which the following is a specification, reference being had to the accompanying drawings, which form a part of this specification.

My invention has for its object certain new and useful improvements in a hydrocarbonburner and water-feed therefor of superior efficiency and utility; and it consists of the construction, combination, and arrangement of devices hereinafter described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a view in side elevation. Fig. 2 is a plan view. Fig. 3 is an end view of the burner, showing parts in vertical section. Fig. 4: is a view of the opposite end of the burner, showing parts in vertical section. Fig. 5 is a view in vertical section through the tank. Fig. 6 is a vertical section illustrating a preferred construction of the valve mechanism, the valve being open. Fig. 7 is a view of the same at right angles to that shown in Fig. 6, showing the valve closed. Fig. 8 is a view in vertical section througl'i the waterindicator, showing adjacent portions of the burner in side elevation, parts being broken away. Fig. 9 is a view in perspective of Fig. 10 is a view in perspective, illustrating a modification in the construction of certain portions of the burner. Fig. 11 is a view in vertical section through the feed-pipe and adjacent parts. Fig. 12 is a detail View showing the communication of the pipe )4: into the burner-pan.

My invention pertains to that class of hydrocarbon-burners in which hydrocarbon fuel is fed to a burner, together with a suitable supply of Water to be turned into steam, the steam and the hydrocarbon fuel commingling in the vapor-generator portions of the device to effectually vaporize the fuel and to supply to the hydrocarbon fuel a suitable quantity of oxygen in order tosccl'lre perfect combustion.

I carry out my invention asfollows: A. water tank or receptacle is shown at (z, supported in any suitable manner, the same communicating, as by a pipe 7), with a steam-generating chamber or pipe 0, which is preferably led along the upper edge of a burnerpan, (indicated at (1.) At the opposite end of said pan from the communication of the water-feed pipe Z) with said chamber the chamber communicates with a return steam-generating pipe or chamber (gas through a connecting-pipef, to a commingling chamber or pipe g, the pipe or chambere preferably extending across the upper surface of the burnerpan. as indicated at it, and communicating with the commingling-chamber g through a suitable union 7:. With said comminglingchamber also communicates a hydrocarbon fuel-feed pipe 3'. The commingling-chamber g at its end opposite the entrance to the fuel-feed pipe j is formed with a downwardlyprojecting portion 7r, communicating with a main burner pipe Z, preferably located in the base of the burner-pan and with which communicates upwardly-projecting auxiliary burner-pipes m and a, provided with any suitable burners at their upper ends,(indicated at p and 1.) These burner-pipes m and a preferably lead upward, so that the flame emitted therefrom will be carried adjacent to any surface to be heated thereabove. The pipe Z is also perforated for the emission of vapor therefrom, which when ignited, as will be evident, will throw its heat upon the steam and vapor generating chambers thereabove, and whereby a portion of the water fed to the chamber or pipe 0 will be turned into steam, and whereby the commingled steam and hydrocarbon fuel in the chamber or pipe 1 will be heated or vaporized. Where it is desired to spread the flame from the burner more widely, the burner at the top of the pipes m and a may be made are shape, for example, as illustrated in Fig. 10.

It will be obvious that by a burner so constructed the water fed to the burner will be vaporized by the heat generated by the burner and that the commingled fuel and steam will also be superheated by the heat of the burner. In the feed-pipe t I locate a water-indicator device, (indicated at 7;) the same being formed with an upwardly -projecting chamber, as shown in the drawings, which is preferably open at the top and within which projects a vertical standard 8 to the required height of the water-line in the steam-generating chamber c. It is also desirable always to have a suitable supply of water within the chamber 0, and the outlet from said chamber into the pipe 0 is sufficiently large to permit the passage of steam from the chamber 0, so that the supply of water in the indicator 2* rising to the height of the standard therein will serve to prevent any back pressure of the steam driving. the water out from the chamber 0. The receptacle a is provided with an inner receptacle 25, within which the water is placed, the receptacle a having a cover, as shown, readily removable for the insertion and removal of the inner receptacle t. The receptacle t is placed in the outer receptacle 0 in an inverted position, as shown, the inner receptacle being provided with a dischargeorifice, (indicated at u,) controlled by a valve 1) upon a stem 10, extended through a cap :0, supported upon the valve-seat y, the valveseat 3/ and cap a; being constructed in a single integral piece, the seat having a threaded connection with the end of the inner receptacle, as shown. A spring 2 exerts its tension upon the valve 1;. The inner receptacle zfis supported upon an adjusting-screw, (indicated by the numeral 13,) as also the outer receptacle 0. The valve-seat u is supported upon the inner head of the adjusting-screw 13 upon lugs 14. It will be evident that when the receptacle t is in place the valve Q; will be opened, allowing the water to be discharged into the outer receptacle (Z. By means of the adjusting-screw 13, which may be passed through a bracket 15 or similar device and having a threaded engagement therein,it will be evident that the height of the receptacles a and twith relation to the indicator 1* may be raised or lowered, as may be required to secure the proper height of the water within said indicator and within the generating-chamber c, the water in the outer chamber a being the same height. It will be seen that when the water within the outer chamber a rises to a sufficient height it shuts off the air from entering through the opening in the valve-seat u, but that when the water-line within the outer chamber (Z descends by the consumption of the water in the generator of the burner an additional supply of water is fed from the inner tank into the outer tank, securing an even pressure of the water-supply, the amount of water-supply being indicated at all times by means of the indicator 7*. The pipe Z may be made in any suitable manner, so that the water-tank (I, can be raised or lowered with relation to the indicator 'r. The pipes m and n are provided with controlling-valves (indicated at 15) adjusted by means of a valve-stem 16. I prel l l fer to construct these valves as indicated in Figs. 6 and 7, in which one of the valves is shown in open position in Fig. 6 and in closed position in Fig. 7, the valve-stem of the valve being journaled in the corresponding pipe, so as to carry the valve in a Vertical position when the valve is fully opened and into a horizontal position when fully closed. I prefer to construct the corresponding pipe with inner shoulders, (indicated at 17 and 18,) against which the valve will seat when fully closed, as indicated in Fig. 7. The auxiliary burners p and q will not need to be in operation at all times and by means of the corresponding valves can be closed ofl, the burner Z still being in operation.

When it is desired to use the burner embodied in my invention in a furnace, for example, I prefer to construct the auxiliary burners supported upon the pipes m and n of a modified form, as indicated, for example, in Fig. 10 at 19 and 20, so that the flame can be spread to a greater extent. It will be evident that the burners may be carried to any desired height by lengthening the pipes m and n.

I prefer that the feed-pipe j should have a removable engagement in the pipe g. While superheated steam supplied to the mixingpipe of the burner will be of sufficient quantity to thoroughly vaporize the fuel and take up all the carbon, still a deposit of carbon to a slight degree might take place, and in order to provide for the ready removal of any carbon that might be deposited the feed-pipe j has preferably a removable engagement with the commingling-chamber. To this end, as shown in Fig. 11, I have shown the pipe 1' having a threaded engagement with a removable pipe 21, as indicated at 22, the pipe 21 having a threaded engagement in the union 7:. By this means the pipe 21, which communicates with the pipe 6, may readily be removed, if required.

I/Vhile the above features embody the essential elements of my invention, I prefer to add thereto, in order to properly hold the flame to secure the thorough heating of the burner, dummies, (indicated at 23 and at 24:, on opposite sides of the pipe 6 and at opposite ends of the burner,) the dummy 23 being provided with supports 25 upon the pipe 0 and the dummy 21 provided with supports 26, resting upon the upper edge of the pan (Z, the burner 24 having two dummy pipes 27 and 28, the one supported upon the other, as by arms 29. The supply-pipe is provided with any suitable controlling-valve 30. It will be understood that when the burner is to be first ignited by opening the valve 30 in the fuelsupply pipe a supply of hydrocarbon fuel is permitted to be discharged through the pipe Z: into the base of the burner-pan, the pipe Z being provided with an opening 31 to permit the fuel passing therethrough into the burnerpan. To hold a portion of the flame down Wmsi upon the adjacent portions of the generatingehambers, I provide a perforated spreader,(in dicated at 32,)the same being shown in Figs. 3 and 4: and omitted in the remaining figures. The burner-pan (Z is also provided with perforations (indicated at 33) to admit theair more readily thereinto toward the base thereof.

It will be perceived that the burners 19 and 20 are connected with the vertical pipe. in, and a by radial pipes 34 and 3 The pipe bat the end toward the receptacle a might be made of lead, the said lead pipe connecting with a union 36. It will be apparent that the water is fed to the steam-gencrating chamber and the feed thereof is controlled entirely by gravity as the water in the steam-generating chamber is vaporized.
